Greece's Problem, South Africa's Solution?

Could the answer to Greece's problems lie in a South-African style amnesty and starting fresh, with an economic rather than racial focus? The idea is more fully explained in this blog post by Dan Ariely. I'm intrigued by how the general idea of reconciliation (and jubilee) applies to both cases. It's worth noting that Ariely is a behavioral economist and so the economic angle is not far from his mind, yet he's making what's ultimately a moral analysis. What I appreciate about Ariely is how seamlessly he integrates the economics and the morals, more successfully (and less preachingly) than most, and with a solid experimental foundation to boot.
